Poindexter

Hold it.that's wasn't Poindexter, that was Sherman. My mistake!
And I see I also misspelled Brainiac (or was it Braniac) in my previous
post. Oh well.just one of those days.

: In the old Rocky and Bulwinkle (Bulwinkel?) TV cartoon, Mr. Peabody
(a time-traveling dog/scientist) had a boy named Poindexter who
wore large glasses and was smart of course. It's probably not the
origin of the use for a "brainiac" -- but it may have helped to
popularize it.

: By the way, the original "Brainac" was one of Superman's alien
nemesis and the original owner of the shrunken Krypton city of Kandor.
